Why aren't my clothes assigned weights? Why can't I assign loose geometry to a bone?
i am in the same hussle, even if you have a bone and a vertex group you hit assign and nothing happends. So frustating, a solution to me is isolate the mesh to an OBJECT (i dont want to do this but...) and select armature, then bone, then object and then parent to bone.
I KNOW that it should work as you explain but i dont know IT dosent, and it is from various version. It is a bug?
